The development of emergency lighting further demonstrates how buildings can be digitally transformed to achieve cleaner, smarter cities. Due to the software and services used to store, process and analyze the collected sensor data, the lighting itself will become more technologically advanced, which has helped emergency lighting transform into today's status and continue to help future industry innovation.
In any study of emergency lighting, there is often an argument about the type of lighting that operates effectively. Some people like fluorescent lights, while others like LED lighting. However, many people have recently concluded that the latter provides better service than conventional fluorescent lamps.

As a representative of      China Emergency Light     , Linsheng will show you why LED technology has advantages over fluorescent technology in emergency lighting. We will also show you the benefits of using LED emergency lighting.

Clear contrast between LED and fluorescent technology
Unless you're in the lighting industry, it can be difficult to tell the difference between tubular LED lighting and fluorescent light types. The similarity is due to the similar appearance of the two bulbs. However, this is a significant difference between the two types of light.
1. LED and fluorescent lamps: longer life?
All lamps have an expected life. This is the time it takes before the failure occurs, and its value is in hours. For T5 fluorescent lamps under constant lighting conditions, the service life may be between 15,000 and 30,000 hours, equivalent to 1.7 to 3.4 years.

Or, LED luminaires have the advantage of unequal latitudes such as longer run times. These lights can operate 50,000 to 100,000 hours without interruption, which is 5.7 or 11.4 years. All in all, LEDs have a longer life than fluorescent tubes.

In addition, T5 fluorescence technology uses electronic ballasts, unlike previous fluorescent techniques using traditional mechanical ballasts. On the other hand, LED technology uses new components in the form of LED drivers.

However, the level of change in the quality of the LED driver and electronic ballast may result in an uncertainty in the expected life of the additional components, resulting in replacement of the entire luminaire. Therefore, users should consider the quality and service life of the product when looking for suitable lighting technology.

2. LED or fluorescent light: cost?
LEDs are a good choice when choosing an economical form of emergency lighting. This is a worthwhile choice because it lasts longer than conventional fluorescent technology. Product costs must be considered when it comes to emergency lighting. In this case, not only should the purchase cost be considered, but the annual functional cost should also be considered. The price of LED lamps for commercial purposes has risen. However, lower operating costs and longer life make fluorescent lamps less popular.

3.LED is more efficient than fluorescent light
Studies have shown that LED lamps are more efficient than fluorescent lamps. The results of an energy-saving study show that LEDs are more efficient because there is no loss on the side of the lamp. In addition, LED lamps consume less power and last longer than other types of LED lamps (Prasopsuk, C. et al., 2018).

Another study on the use of 6-watt LED lights for about 5.93 hours showed that the energy savings were about 66.12%. These lamps replace the use of 13-watt compact fluorescent lamps (Supawong, U. et al., 2016).


4. Directional light source
Unlike the 360-degree mode associated with fluorescent lamps, LEDs using LED technology emit light in a 110 degree mode. However, when tubular fluorescent lamps are used, only a small fraction (about 30%) of the discharge light will reach the desired target. This shows that we are not using all the light from fluorescent bulbs because they also brighten the fixture. ( reasons to consider leading the replacement bulb - vs-t8 fluorescent bulb /)

5. Brightness
Unlike fluorescent lamps that burn out or go out over time, LEDs maintain their brightness for longer periods of time. This happens because the lumens are reduced, ie the slow dimming of the LED light intensity.

6. Heat
LED lighting products emit light through their energy. On the other hand, fluorescent lamps use heat to generate light, making it unpopular among homeowners.

7. Impact on the environment
We can see another difference in the presence of mercury in fluorescent lamps. According to Aucott et al. (2003), when an abandoned fluorescent bulb ruptures, it releases a large amount of toxic mercury gas into the air. This will pollute the environment. However, LED lamps do not contain glass or mercury, making them a safer alternative to lightning (Stevens R et Motta M, 2018).

8. Color development
LED lights match natural light. This similarity occurs because the LED chip contains a representation of all colors and displays the brightest white. It also emits every color like the sun. However, because the wavelength of a particular color produces spikes, the fluorescent light renders less and does not mimic sunlight.

9. Benefits of using LED technology for emergency lighting
With the advantages of the aforementioned tubular LED illumination, problems with the advantages of LEDs as an ideal source of emergency lighting should be envisioned.

LED lights actually meet the criteria for each photometric parameter. The end of life of LED lighting is its advantage, while having amazing energy-saving capabilities. In addition, LEDs are becoming more popular among designers and architects as LEDs are associated with more fashionable emergency light forms.

Now let's take it a step further and learn how LEDs can achieve emergency lighting and make it the best choice for installers and users.

10. Long-term cost is cheap
Compared to other light sources, LEDs can be at a disadvantage due to installation costs. However, LEDs have a higher status when considering the entire cost of life. For example, comparing a conventional 8W maintained stand-alone bulkhead with the same wattage of LEDs, the cost comparison ratio is 1:2 or 1:4, respectively.

A rigorous evaluation of the cost of replacing the two light sources and batteries for eight years also makes LEDs a suitable choice. During this time, both sources need to be replaced. However, the 8W fluorescent bulkhead needs to be replaced twice. This requirement burns a hole in the user's pocket because each replacement of the bulb equals the initial cost of the partition from the expensive labor and collection costs.
11. Put safety first
Emergency lighting is required in so many places around buildings or in underground parking lots in buildings. Emergency lights allow people to move people quickly and safely during difficult times such as fires. Therefore, the presence of an appropriate exit light indicates an exit path to prevent panic.

In recent years, LED modules that can replace fluorescent lamps have become popular among installers and users. These lamps are low cost and efficient, making them a sought after product in the emergency lighting industry.

LED systems have so many positive characteristics that the technology is likely to be the ideal source of light. Because it does not contain environmental toxins such as lead or mercury, LED lights do not have any negative impact on the environment. In addition, its non-volatile properties make it a valuable material in what is considered an explosive environment, such as an explosive atmosphere. Mines and oil rigs.

Due to their energy efficiency, LED illuminators can be operated with backup batteries or generators that start up when power is lost. LED lights are used as point sources, so it's easy to direct them where they are needed. This combination of high optical efficiency increases energy efficiency.

12. Saving energy
LED-based emergency lights also have an advantage in terms of energy consumption. LED lamps consume only a fraction of the energy required for fluorescence technology and have the ability to further reduce energy consumption through intelligent dimming technology.


13. No need to replace as much as fluorescent light
As mentioned earlier, the cost of replacing the 8W fluorescent emergency light lamp exceeds the cost of installation, considering the labor involved. Alternatively, LED-based lamps do not require much modification during their lifetime.

In addition, before the fluorescent lamps reach the end of their useful life, they will decrease over time, and their amount of luminescence is lower than their rated output. However, when using LEDs, degradation is slower and therefore critical for emergency lighting.

Increase lighting for high-risk tasks with lighting controls
It is well known that LEDs provide directional light to make light distribution easier to handle. This control allows light to move to where it is needed, such as escape routes and open areas.

14. Reduce the heat of emergency lights
As LED efficiency increases further, these devices generate less and less heat. Similarly, the current trend of using more medium power LEDs instead of high power LEDs also reduces the amount of heat generated. Less heat is generated, keeping the battery at a lower temperature, making the LED suitable for independent lighting, ensuring longer product life.

Provide better light quality
A light source with a color rendering index (CRI) greater than Ra 40 performs well when looking for an ideal source of emergency lighting. At such low requirements, we can see that the quality of emergency lighting does not necessarily have to be of a high standard. However, since the main lighting requires better light quality, there is a tubular LED illumination with a higher CRI to meet this demand.

After understanding the importance of LEDs as an emergency lighting source, let's look at the relevance of LEDs to smart buildings.

15. The benefits of LED technology for smart buildings
LED lights can be used as a means of digital communication and create a cable intelligent building network.

The following are some ways in which intelligent LED lighting can benefit a variety of structures through IoT connections.

Improve public and family safety
Chaflin et al. (2017) pointed out that lighting can reduce crime rates by 39%. This makes the use of intelligent LED lighting a relevant measure to improve safety. Street lights with LED technology can help create a network that allows captured data to be used for intelligence and extensive surveillance. For example, in Los Angeles, smart street lights have reduced crime rates associated with vehicle theft by more than 10%, burglary and vandalism.

16. Help improve energy efficiency
Structures with traditional light sources need to switch to smart LED lighting systems to meet the changing needs of their occupants.

Integrating LED lighting systems with IoT creates an excellent opportunity for budget management and energy savings. Reducing power usage can cut costs, which is good for both home and office buildings. The use of LEDs also reduces greenhouse gas emissions.
The last sentence for you
Lighting plays an important role in modern architecture, and LEDs and fluorescent lamps are potential choices for builders. Despite the lower cost of fluorescent lamps, LEDs have lower maintenance costs, emit less heat, are free of toxins, and consume less energy. These features make LED lights ideal for emergency lighting.

LEDs also have the advantage of being easily integrated with wireless technology to form networks with various devices to create intelligent lighting systems. Intelligent LED lighting systems still have many applications in the construction industry. These include ensuring energy efficiency, safety and predictive maintenance.
